Twecomm TC-831 is a high quality, ultra light weight stereo and mono audio
distribution system that is especially well suited for furnishing mic or line level press feeds.
This dual channel unit is easily switch configured to provide either eight ( 8
) stereo or dual channel mono outputs, or sixteen (16) mono outputs. Each of the front panel male XLR output connectors can provide either a microphone or line
level output signal that is individually switch selectable per output. All outputs have individual, low impedance, active balanced output drivers.
Shorting an individual output will have no effect on any of the other
outputs. RF suppression is provided on all inputs and outputs.
An additional feature is the ability of the TC-831 to “sum” a stereo input signal and provide a mono signal to each of
the 16 outputs.
panel, multi color bar graph meters provide a visual indication of signal activity and are also used to
calibrate operating levels. The bar graph meters can be jumper selected to operate in either a progressive
“bar” or “single segment “dot” mode. Front panel LED’s indicate if the unit is configuration for stereo or
mono operation. System operating levels are set via front panel, recessed gain trims.
rear panel balanced, bridging inputs feature looping male and female XLR connectors for “daisy chaining”
multiple TC-831 units or connection to external monitoring equipment. A ground lift switch is provided to
disconnect, or “lift” system ground from pin 1 of all XLR input connectors, while carrying pin 1 through to
the other looped connector.
TC-831’s all aluminum construction makes for a robust yet extremely lightweight
package. The internal wide range power supply allows the unit to
be operated anywhere in the world from mains voltages ranging from 67-260 VAC, 40-400 HZ. The internal power
supply is UL approved and is also approved by other recognized worldwide testing
organizations. Mains power is supplied via the rear panel
IEC fused / switched power receptacle. An IEC north American style power cord is furnished with
